TECHNICAL FIELD

[0001] The utility model relates to physiotherapy equipment technical field, specifically is a cold and hot piezoelectric composite physiotherapy equipment. BACKGROUND

[0002] Cerebrovascular disease caused by brain blood circulation supply disorder is collectively referred to as stroke. Early stroke patients generally have symptoms such as limb weakness and confused consciousness, and if they do not receive timely and effective treatment, they are prone to complications such as muscle atrophy, joint stiffness, and limb swelling. Stroke patients should start rehabilitation as early as possible to help recover from sequelae, and the earlier the rehabilitation, the better the recovery. However, if not treated in time, many complications may occur, such as joint infection, limited mobility, and muscle atrophy; if the rehabilitation treatment is not regular, it may also cause the upper limbs to become spherical and the lower limbs to form a circle gait, which seriously affects the patient's quality of life.

[0003] Rehabilitation training for stroke has been widely used, but it is not usually done immediately in the early stage, but rather after several months of clinical treatment, the patient is transferred to a rehabilitation clinic, so it is easy to miss the best treatment period in the early stage. Early rehabilitation training for stroke is also an essential part of the treatment process! The disability rate of stroke in the United States, also known as "stroke", is about 30%, while in China, the disability rate is as high as more than 75%, the main reason being the lack of rehabilitation treatment for patients. The development of therapeutic instruments and equipment for stroke patients has significant social and economic benefits in reducing disability, restoring patient function, and protecting human dignity.

[0004] Related literature shows that cold and hot alternating stimulation can treat pain and swelling, relieve muscle tension, and is an effective method for treating spasticity and swelling in stroke patients and promoting motor function recovery. Under the joint support of the National Key R&D Plan 2020AAA0109605 and the National Natural Science Foundation 61873066, 62173090, Southeast University developed a wearable cold and hot stimulation rehabilitation system for stroke.

BMC Musculoskeletal Disorders, https: / / doi.org / 10.1186 / s12891-022-05623-z)".
